The education system is developing and changing

Under the wise leadership of our friendly Hero Serdar, modern and positive reforms are being carried out in all areas during the Revival of the new era of the Stable State. In developed countries, ways to improve the efficiency of general education are being sought, and a lot of work is being done to develop advanced technologies and introduce them into the education system. The technological support of modern education should correspond to the level of advanced science. In recent years, educational centers built in the country have been provided with computers and Internet connection. Schools, kindergartens, higher and secondary vocational schools equipped with the latest equipment are operating in our capital, regional and district centers. The provision of educational centers with interactive multimedia technologies has led to a radical improvement in the quality of education. Multimedia technologies allow the presentation of information in various forms, ensuring the effectiveness of the lesson. The service of multimedia technologies in the lessons is great for students to thoroughly master the topics, to expand their horizons, to develop their expression skills, to learn to work creatively and independently, and to improve the quality of education. When the lessons are organized with multimedia technologies, it can be seen that young people have a deep understanding of the topic, their memory and attention are activated, and their creative skills develop. It also increases the creativity of educational workers and helps to save their time.

This testifies to the development of science and education, which is the source of our development and success in our fatherland. May our friendly hero Sardar, our national leader, who cares deeply about our future generation, be healthy, live long, and enjoy his hard work!

The role of fertilizer chemistry in the intelligent specialization of the country's agricultural development.

1. Bulk chemical industry.More than 70 elements are found in plants, most of which are found in very small amounts. However, elements such as carbon, oxygen, hydrogen, nitrogen, phosphorus, sulfur, magnesium, potassium, and calcium are also abundant and essential for life. Plants can obtain nitrogen, phosphorus, and potassium (NPK) from the air and soil. However, these three elements (NPK) are supplied externally to the plants for good yield. Fertilizers are used to enrich the soil with NPK.Organic fertilizers. In them, nutrients are stored in substances of animal and plant origin. First of all, these fertilizers include manure, as well as various products of the processing of substances of animal and plant origin (peat, fish meal, feces, urban waste and various food wastes).Bacterial fertilizers - retain microorganisms that facilitate the accumulation of nutrients in the soil.2. Mineral fertilizers - products of inorganic origin, prepared by the industrial-factory method: chemical or mechanical processing of inorganic raw materials (for example, extraction of minerals - phosphorites, potassium salts, dolomites, etc., etc.). .). Mineral fertilizers obtained by chemical processing of raw materials differ in the concentration of active substances. Mineral fertilizers are divided into the following groups according to their active ingredients: nitrogen, phosphorus, potassium and micronutrients (boron, molybdenum, etc.).Along with the increasing demand for fertilizers, the production of NPK and NPK compounds has also increased. Many mineral fertilizers (for example: KCl, NaNO3, NH4NO3, etc.) contain only one nutrient. Such fertilizers are considered simple. Mineral fertilizers with two or three primary nutrients (NPK) in their composition are more complex. They belong to complex fertilizers.Air (raw material for nitrogen), phosphate rock (raw material for phosphorus) and sylvinite (raw material for potassium) are used as the main raw materials for fertilizer production.Elements   Duty NitrogenIt is stored in proteins. Deficiency causes slow growth..PhosphorusIt is stored in the composition of nucleic acids. It is necessary for the growth of roots. It helps in energy exchange during exposure.PotassiumAccelerates photosynthesis. Increases hydrocarbon production..The main functions of N, P and K elements as fertilizers Fertilizers are divided into simple and complex fertilizers according to the nutrients stored in the system. Simple fertilizers include nitrogen, phosphorus and potassium fertilizers. Simple nitrogen fertilizers include ammonium nitrate NH4NO3, urea (NH2)2CO and others. Simple superphosphate Ca(H2PO4)2•2CaSO4, double superphosphate Ca(H2PO4)2 and others are simple phosphorus fertilizers. Simple potassium fertilizers include potassium sulfate K2SO4 and others.
